Abstract A liquid crystal eutectic is reported that has refractive indices matched to silica at 25°C and 1.3 mümi with the n 0 below that of silica and n c above. It is demonstrated that the refractive indices of the eutectic allow a polarization filter, operating at telecommunications wavelengths, to be made on a silica-fibre based half-coupler block.
